Ingredients

Scale

Main Ingredients:

  • 1 package frozen hashbrowns
  • 2 cups shredded cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 2 yellow onions
  • 1 can cream of chicken soup

Supporting Ingredients:

  • 1 packet French onion soup mix
  • 1 cup sour cream
  • 4 tablespoons butter
  • 2 cloves garlic
  • 12 tablespoons olive oil or butter

Topping:

  • 2 cups crushed cornflakes
  • Salt and pepper to taste

Instructions

  1. Preheat your oven to 375°F and generously grease a 9×13 inch baking dish with 2 tablespoons of olive oil or butter.
  2. Melt 4 tablespoons of butter in a large skillet over medium heat, spreading the butter evenly across the pan’s surface.
  3. Add 2 thinly sliced yellow onions to the skillet, stirring occasionally until they transform into a rich, golden-brown color, which takes approximately 15-20 minutes.
  4. Drop 2 minced garlic cloves into the skillet and sauté for an additional 60 seconds until their aroma becomes wonderfully fragrant.
  5. Remove the caramelized onion and garlic mixture from heat and let it cool slightly.
  6. In a spacious mixing bowl, combine 1 package of frozen hashbrowns, 1 cup sour cream, 1 can of cream of chicken soup, 1 packet of French onion soup mix, 2 cups shredded cheddar cheese, and 1 cup shredded mozzarella cheese.
  7. Fold the cooled onion and garlic mixture into the hashbrown mixture, seasoning with salt and pepper to your taste preference.
  8. Transfer the entire mixture into the prepared baking dish, spreading it evenly to ensure consistent cooking.
  9. Scatter 2 cups of crushed cornflakes across the top of the potato mixture for a crispy, golden topping.
  10. Bake in the preheated 375°F oven for 45-50 minutes, until the top turns a deep golden brown and the edges become bubbly and crisp.

Notes

  • Caramelize onions slowly and patiently to develop deep, rich flavor that transforms this classic potato dish.
  • For a lighter version, swap half the sour cream with Greek yogurt and use low-fat cheese.
  • Prepare the casserole ahead of time and refrigerate – the flavors will meld beautifully when baked later.
  • Use a mandoline or sharp knife to slice onions uniformly, ensuring even caramelization and perfect texture in every bite.
